About Biotic Environmental Factors

Biotic environmental factors include:

• Diseases
• Large populations;
  • Consuming too much food.
  • Using too much of the fresh water
  • Blocking out light
• Parasites

Examples

Disease is a biotic factor which can lower the population of a specific organism within a community. This will have an effect on other organisms in the community due to the feeding relationships between them. If a disease reduces a population then the population of the organism that eats it will decrease while the population of organisms that are eaten by it will increase.
